power factor correction and power line filters to keep the power clean. These filters were very noisy for employees working in
the equipment room for long periods.

High Reliability. Advanced design including use of medium voltage Insulated Gate Bipolar Transistors
(IGBTs), oil-filled capacitors, a built-in copper wound transformer, and surge and transient protection

Low Harmonic Distortion. The 24-pulse rectifier’s low harmonic impact of less than 1.5% distortion
gives clean operation without the use of filters, allowing the original filters to be disconnected.

High Power Factor. The new system has a very good power factor of better than 0.95 and does not
require any external power factor correction equipment.

Compact Drive. The Dura-Bilt drive system fits in a smaller space than the original system because
the transformer is integrated into the cabinet and the heat pipe cooling allows a very compact drive.
